I noticed the CDC is the 'Tier VIII of the week' this week, and WG's description made me chuckle;

"The AMX CDC is a highly mobile support vehicle box of free hit points, capable of damaging the enemy reliably sometimes.

Thanks to its amazing gun "gepression" average Tier VIII premium medium gun depression, it can hide most of its profile and perforate the enemy the air around the enemy, while they miss most of their shots penetrate every single one of their shots - even when they fire HE!"
